IMAGE CORRECTION PROGRAM, IMAGE CORRECTION DEVICE, AND IMAGE CORRECTION METHOD

摘要

An image correction device (10) extracts a dark pixel region of image data to calculate the area of the dark pixel region. Subsequently, the image correction device (10) calculates the distribution of the brightness values of the pixels from the gradation in the extracted dark pixel region. The image correction device (10) then determines whether the area of the dark pixel region is larger than a predetermined threshold and the distribution of the brightness values of the pixels is larger than a predetermined threshold. As a result, the image correction device (10) performs brightness conversion as an image correction by using a LUT (14a), when it is determined that the area of the dark pixel region is larger than the predetermined threshold and the distribution of the brightness values of the pixels is larger than the predetermined threshold.
